I've read your proposal, and it immediatelly reminded me about openbsd's
securelevel(7). Wouldn't Openbsd count as an example, where a
potentially unsafe system is booted, and secured it has booted? Doesn't
it all depend on the kernel/interpreter?

Compare:
  http://www.openbsd.org/cgi-bin/man.cgi?query=securelevel&sektion=7
With:
  http://www.rubycentral.com/pickaxe/taint.html

For me, it sounds quite comparable, 'same old procedure', and the same
result: "start an untrusted system and secure it afterwards...

Or am i missing something? (right now, that's quite possible *lol*)
